one Phison PS8007-A SD-to-Flash bridge (search for phison PS8005 on google for a close datasheet)

one STFM1000 fm tuner chip, there is no available datasheet due to a patent but the freescale i.MX linux source code has a driver for it (search for stfm1000 linux on google). The product brief can be found on Freescale website

A chip marked 263 M121, which is probably a Freescale MPR121 Proximity Capacitive Touch Sensor Controller, the datasheet can be found here

One bluetooth module made of a flash chip holding the firmware and BlueCore5?-Multimedia External BC57E687C? (there is a technical preview on google)

one XPT8302, a 4W class D audio amplifier for the speaker

the LCD controller seems to be (or be compatible with) the OTM2201A? of which the datasheet can be found here (or look for "OTM2201A datasheet" on google)

Recovery mode

The Creative Zen Style X-Fi3 has two recovery modes:

One software recovery mode which can be entered by holding volume down on boot, but which is of little interest

One hardware recovery mode (the STMP3780 one) which can be entered by plugging usb while holding power (ie holding the power slider) on (at the same time). Alternatively, it can be entered by plugging usb, holding power and pressing reset (while holding power). The screen will stay black and the device will enumerat has 066f:3780 from Sigmatel. Inc
